Whether you come by your white smile naturally or with some help from teeth bleaching products, the easiest way to keep them that way is to avoid teeth-staining foods. Dr. Jeffrey Rappaport of Lavaan Dental Spa in New York tells us some of the most common Latin ones.

Sangria

A good rule of thumb: if a food could stain a white shirt, it will stain your teeth. Blame the tannins in red wine. Opt for white sangria instead — it's just as amazing.

Coffee

If you can't stand to go without you daily dose, make sure it's heavy on the leche and rinse your mouth afterward.
